Adjacent to the upper edge of the ashpit 18, are provided supports 18, 18,

to receive and su port a grate 18".

The body portion 16, of the stove is comi `tubes 2l, 21,. connected together by intey grally formed webs 24, 24. Vhere the tubes are of greater length, or where a panel of 4one length is to be connected with a panel of diii'erent length,

one or more intermediate headers or connecting sections as 25, may be provided.

The vertical edges of the frontnand rear panels 20, 20, are provided with rearwardly and forwardly' extending flanges 20", 20h, respectively, which are bolted o1` otherwise secured to the projecting web portions 24, 24;", formed at the front and rear edges of the side panels 20, 20.

The front panel 20, has the webs connecting the tubes cut away adjacent to its lower end, to form a series of vertical openings 20c, 20", constituting a vertical grate which is closed by a tire door 26, and the rear panel 20, adjacent to its upper end, has portions of the webs connecting the severaltubes cut away to form a series of vertical openings 20d, 20d, leading to a smoke box 26, which is suitably scoured at one end to the said rear panel, and has its other end 26", formed to receive one end of a smoke pipe or flue leading tothe chimney.

27 denotes a hollow, rectangular connecting member `which is secured in, the topof the stove, and is connected by nipples 28, 28 with the four headers 22, 22, provided at the upper ends of said panels 20, 20, in order to exchange ci fluid in said panels and the tubesthereof. The rear nipple has its outer end threaded to receive a cap or plug' 28a.

29 denotes a similar hollow, rectangular connecting" member which is secured to the lower ends of the panels 20, 20, by four nipples 29, 29". The nipple 29 of the rear panel 20, has its outer. end screw-threaded to receive the end of a return pi e 29, andthe upper rectangular member 2 is provided ini'ts upper surface witha threaded opening 30, to receive an outlet pipe 31, leading to the heating apparatus, and a semi-circular fuel opening 32,`provided with a hinged cover 33.

The lower surface of the ,upper rectangular member 2, is provided with a dependm flange 3st, within which is suitably secure the upper end of a fuel magazine 35, Whose lower end extends downwardly into the stove `and terminates at'a point sufficiently above the grate tto' provide a combustion chamber 36.

36 denotes an angular collar, which is secured upon the lower end of the fuel magazine and serves to reinforce the same at that point.

Upon the inner side of the rear panel 20, about midway of its height' is. arranged la horizontal partition or baiile plate 37, which extends forwardly to the rear wall of the fuel'magazine 35, and at each side of said fuel magazine 35, is disposed an angular baiile plate 38, comprising a vertical section 38, and a horizontal section 3S", whose rear end terminates adjacent to the forwardedge of the horizontal baille plate 37.- V j 39, 39` denote auxiliaryair inlets which may be provided in the webs 24, 24, in one lor more of the panels 20, 20 at such point or points above the grate as will best insure the proper mixture of air with the gases 4 `liberated in the combustion chamber.

Each panel 20, 1s composed of a plurality of separated thin walled tubes, whose metal line isof such predetermined or calculated thickness, and whose external diameter is of such proportion as to give a low value to the f ratio which the transverse cross sectional area of said metal line bears relative to the external surface per unit length of tube.

When it is desired to use the apparatus only as a secondary heater, the same may be vinclosed by an outer shell or jacket 15,-

and a lining of asbestos 15b, as indicated in Fig. 5, in order to prevent the ap )aratus imparting any material amount of its heat to the chamber within which the same is located. l

At Figs. 6, i' and 8, I have shown aseries of modified forms of panels and tubes. In the construction illustrated at Fig. 6 the tubes 20', 20 are shown connected by webs 24', 24', arranged eccentrically.' At Fig. 7, thetubes 20e, 20e are shown connected by intervening webs 24e, 24e, which are arranged centrally of the tubes, and upon the outer surfaces of said tubes are provided vertical, longitudinal ribs 252 25x. Fig. 8, the tubes 20', 20 arev shown as substantially U-shaped in cross section, and their ends formed 'ntegrally with webs 24, which in this instance form a flat plate on one side.

At Fig. 9 is shown a panel having parallel, vertical tubes 20, 201, and the panelrprovided at its middle adjacent'to its lower edge with an inlet opening 28", and adjacent to its upper edge with an outlet opening 30".

At Fig. 10 is shown a modified form of panel, in which the tubes 20,l 208, are arranged in inclined position and `parallel to each other. la this construction the inlet o ening 28Ik is arranged at the base of the p atc adjacent to one of the vertical edges of lthe panel, ond' the outlet opening, ellishown at Figsi 12-zmd 13,1 have Illustrated arefr'nade ofr solid material, ysfu'eli es' rnettl',` fire" brick, tile or other suitable materialfand'j only the trov sidewells'formed' of 'panels' r20g 42, 42 of' said side panels 40,*40 ,arefjpro- (by integrally formed webs; 49,2493 'In'fthis over' which the Lheated 'gases`- and 'prodiiet-s of number of said-'pe e s mayber varied andl the arrengementend angles thereof alteredv u, 'eccording totheseapecity demandectv .vening ytransverse panel '47,jhayngverticl opposite longitudinellsdesof.sai [tubes,ff18,`,.ineintained in seperated?relationy eornnumc'ntin With'seid hollow con *construction* the :upper edge of the "transf` verse-.panel 4&7` is dlsp'osedin'ja horizontal .position somewht fbelow the) upperfedge's of the side panels', `s o as 'to form' en1tlet'- comprising a hol heaterfat, plnral;
